i "Application filed April 13,

My invention relates to wind deflectors and refers part-icularlytodevices of this character adapted to be positioned-with n a window frameand to deflect the air passing material'for the production of winddeflectors. as it is cheap, can be shipped in-flat form and easilybentinto the desired shape, is light and can be made water proof bymeans of paint or varnish. i h

"Corrugated cardboard, however, is not practical for the purposesindicated as wind deflectors must be attached to window frames,preferably by means of nails, or screws. The formation of corrugatedcardboard is of such character. that the headsof the fastening means areforcedinwaidly of the cardboard in attaching the latter to a windowframe, thus preventing a "tight joint-ure. Y

. Another undesirable feature of corrugated cardboard for this purposethat the cardboard is liable .to tear awayrfromthe fastening means, anypressure or strain hav.- ins; a tendency to pull the naih or screw,through the cardboard, thus destroying the usefulness of the device. 1 Q

My invention allows the use ofcorrugated cardboard for wind deflectorsasit overcomes the objectionable properties above described andcompletely prevents the entry of the heads of the nails, or screws fromentering the cardboard, thus allowing firm connections between thedevice and the windowv frame and also completely overcoming thepossibility of a cardboard tearing away from the fastening means becauseof strains, or stress, brought to bear upon the device.

My device comprises a corrugated cardboard Wind deflector, the fasteningportions of which carry a metallic strengthening member, or strip,having holes therein through which the fastening means may be inserted.The inner edge of the strengtheningmeans carries a plurality of teethinserted within the cardboard. Any strain, therefore, upon the device isnot brought to bear simply upon the nails, or screws, used forfasteninpur JOSQS. thus tendin to'tear b a I the fastening means through thecardboard, but such strain is supported bythe plurality of teeth andhence distributed-over the entire metal strengthening member.

' It willthus be seen that my device over- 7 comes the inherent weaknessof the corr gated cardboard and presents a. deviceof great value andusefulness.

The particular form of the device of my invention shown intheaccompanying draw- .ingsgcomprises a blank of corrugatedcardboardscored and bentalong the lines A-A an d .;B *B,. thus formingthe 'front, member 10. and the two triangular side members 11 and 12.

A metal strengthening member 13 of U shaped construction, having theinwardly exn tended staggered teeth 14, 14 is placed around the uprightedge of each side member 11 and 12 and the teeth 14, 14 pressed inwardlyinto the corrugated cardboard of which each side member is composed.

I The two series of teeth 14, 14 in addition to being staggered withrespect to each other are offset with respect to each other bymaking'one side of the member 13 slightly longer than the other side. Thesestaggered and off-set positions of the teeth are desirable as theypreserve the strength of the corrugated I cardboard, which wouldotherwise be weakened by the inserted teeth.
